WINDSHIELD CLEANER Filed Ma 1, 1933 Patented Nov. 13, 1934 UNITED STATES PATENT OFFICE 3 Claims.

My invention has for its object to provide a windshield cleaner capable of resisting climatic conditions to prevent the deposit of moisture,

snow, frost and rain on window panes, and to remove such moisture, snow, frost and rain as may be deposited thereon. The said invention is particularly adapted for use with windows,

Windshields and the like to keep the view through same suficiently unobstructed to permit of clear vision for the operator of the vehicle.

With the above and other objects in view, I have provided a windshield cleaner comprising a disk that is operated by an enclosed fan, or air pressure forced thereon and the said disk so constructed to force a current of air on the windshield to prevent the accumulation of moisture, snow, frost or rain thereon.

With the above objects in view the invention consists in certain peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawing and appended claims.

In the drawing:

Figure 1 is a sectional side elevation View.

Figure 2 is a part sectional View from the back.

Figure 3 is a sectional side elevation view of a modified method of operating my invention.

Figure 4 is a back View of Figure 3.

Figure 5 is a sectional view of the valve closed, which valve is used to control the operation of my device.

Figure 6 is a sectional view of the valve opened, which valve is used to control the operation of my device.

Referring by characters to the drawing, I represent the Window or windshield by the numeral 2. The window 2 is drilled at a determined point and a bushing 3 is inserted through the windshield. The bushing is threaded on the outside and held in position by means of the nuts 4. The inner end of the shaft 1 is provided with a fan consisting of fan blades 9 which are sweated or brazed to the shaft at about 120 degrees apart and enclosed in a casing 8. The shaft rotates through the casing 8 on the bushings 18. A small pin 19 is inserted through the shaft 1 to hold the fan in position. The fan blades are twisted so that the air pressure will drive the fan in the proper direction.

The outer end of the shaft 1 is threaded and a disk 5 is secured thereto by means of the nuts 4, and may be secured thereto at any predetermined distance from the window or windshield 2. The disk is provided with V shaped slots 12 and one side of the slot turned over, as indicated by the numeral 6, to force a current of air against the window or windshield 2 when the disk 5 is revolving. The disk is composed of transparent material and may be constructed of bakelite or similar material.

The power to operate the fan blades 9 is provided by the inlet pipe 11 which is connected to a source of power, and the air or gas after passing through the fan passesout through the outlet pipe 10.

In Figures 3 and 4 I have shown a modified means to operate my invention in which I have placed the fan casing 8 below the window 2 and supported to the frame 16 by means of a brace 17. A fan shaft 15 extends from the fan and is provided with a bevel gear 14 which meshes with a bevel gear 13 on the driving shaft 1.

What I claim is:

1. In a device of the class described comprising a transparent fixed disk supported adjacent a window pane, said disk provided with a beveled edge to carry rain or moisture to the bottom of said disk, a transparent movable disk support adjacent said fixed disk, means to operate said movable disk by air pressure acting on slots inserted therein.

2. In a device of the class described comprising a transparent fixed disk supported adjacent and against a Window pane, said disk provided with a bevel edge with said beveled edge extending from said window pane to provide means to carry rain or moisture around said beveled edge to the bottom of said disk, a transparent movable disk supported adjacent said fixed disk, means to operate said movable disk from air pressure acting on slots inserted therein.

3. In a device of the class described comprising a transparent fixed disk provided with a beveled edge and supported adjacent a window pane, a transparent movable disk supported adjacent said fixed disk, means to operate said movable disk from air pressure acting on beveled slots inserted therein.
